Thank you for purchasing an Azbil Corporation 200/300 Series Smart Valve Positioner. Smart valve positioners in the 200/300 Series (also referred to as the 200/300 Series in this manual) can be connected to a 4 to 20 mA signal line. Since all adjustments can be performed electrically using CommStaff, any desired relationship can be set between the input signal and the position of the control valve. Split range and other special settings are also easy to specify. This manual describes the use of the Smart Valve Positioner. Use this manual to get the most from the features of the device.

Cautions to ensure safe operation
Do not perform wiring work, turn on the electricity, etc., when your hands are wet. ere is a risk of electric shock. Perform this work with the power supply turned o, and with dry or gloved hands.
Aer installing the device, do not place your body weight on it, use it as a scaold, etc. ere is a risk that it could fall over.
Do not touch the device unnecessarily while it is in operation. Depending on the environment in which the device is used, there is a danger that the surface of the device may be very hot or very cold.
When opening the cover of the terminal box, be careful of the edges of the cover, the threads of the screws on the main unit, etc. ere is a possibility of injury.
Use a DC power supply that has overload protection. An overload can cause the emission of smoke and re.
Bringing tools and the like into contact with the glass portion of the display can cause damage or injury. Exercise sucient caution. In addition, be sure to wear safety glasses.
As this product is extremely heavy, watch your footing, and be sure to wear safety shoes.
When the device is in operation, do not touch moving parts such as the feedback lever. Your hand may become caught, resulting in injury.
Supply power correctly based on the specications. An incorrect power input can damage the instrument.
When working in a high-temperature or low-temperature environment, wear gloves and other protective equipment.
Do not bring magnets or magnetic screwdrivers near the device. ere is a possibility that the control valve will move in response.
When working in a hazardous area, perform installation and deployment according to the construction methods prescribed by the guidelines for the guidelines for the hazardous area.
For ameproof explosion-proof specications, do not under any circumstances open the cover during operation (when powered up).

Combination of model AVP300/301/302 (integral type) and single-acting linear diaphragm actuator1. Attachment of feedback leverIn order to minimize the risk of damage to the feedback lever while it is carried or transported, and to minimize the packaging as well, the feedback lever is detached from the body of the device when it is packed. As a result, the feedback lever must be attached to the body of the device prior to installation of the device.
The length of the feedback lever can if necessary be adjusted by attaching the extension lever between the feedback lever and the body of the device. Adjustment of the feedback lever length is determined based on the form of the actuator.
When connecting an actuator other than those in the table, connect the device and the actuator, and then switch to manual mode and move the actuator slowly and ensure that the feedback lever does not interfere with the full stroke of the actuator.
If the feedback lever alone cannot cover a full stroke, attach the extension lever to it.
Attach the feedback lever securely, working from the front of the device, using the two included hexagon socket head bolts.
Attachment of Feedback Lever
Attach the extension lever securely, working from the front of the device, using the two included hexagon socket head bolts. Then, in the same way, attach the feedback lever securely, working from the back of the device. (The feedback lever can be attached from the front as well.)
Attachment of Extension Lever and Feedback Lever
2. Attachment and installation Attachment to the actuatorAttach the actuator to a mounting plate that is appropriate for the actuator. Adjustment of attachment positionsProcedure for adjustment of attachment positions
Step Procedure1 Set the A/M switch to manual operation.
(See 5.2, A/M Switch.)2 Supply air, and adjust the actuator air pressure such
that the actuator stem reaches the travel midpoint.3 Adjust the actuator such that the feedback lever
reaches a 90 angle to the device's central vertical axis. Depending on the actuator being used, adjustment may be performed by moving the device, or it may be performed by moving a pin.
4 Set the A/M switch to automatic operation. (See 5.2, A/M Switch.)
The accuracy specifications can be satisfied by making the attachment angle 90 2.
If the actuator type is specified when ordering, and the extension lever is included:
Attach the extension lever to the body of the device, and then attach the feedback lever.
If the actuator type is specified when ordering, and the extension lever is not included:
The extension lever is not necessary. Attach the feedback lever directly to the body of the device.
If the actuator type is not specified when ordering:
